Let’s say your new at some organization and you need to be sure of the Directory Services Restore Mode password.
Here’s how:
Open a command line and type ntdsutil.
At the Ntdsutil command prompt, type set dsrm password.
At the DSRM command prompt, type one of the following lines:
To reset the password on the server on which you are working, type reset password on server null. The null variable assumes that the DSRM password is being reset on the local computer. Type the new password when you are prompted. Note that no characters appear while you type the password.
-or-
To reset the password for another server, type reset password on server servername, where servername is the DNS name for the server on which you are resetting the DSRM password. Type the new password when you are prompted. Note that no characters appear while you type the password.
When your done, just quit by typing q at the DSRM command prompt, and then at the ntdsutil command prompt.
